I had a code on mine no matter how many parts I threw at it, it wouldn't go away. Eventually the valve dropped.

Give me a few to find the thread for it.

Do you know what code it was and what cylinder did your valve seat drop in? I've heard the #4 cylinder is the most common to drop a valve seat followed by the #2. The code P0171 is for the #1 cylinder so I would assume that would be the cylinder with the problem but I've never heard of a valve seat dropping on the #1 cylinder.

It can drop on any.

I still don't think it's a seat issue. It wouldn't run lean on that cylinder anyway, it would run rich.

I would be looking for an intake manifold leak if it's on a single cylinder. of course, just because it only has the code for one cylinder doesnt mean it's the only one.

For the record, mine would randomly run like crap no matter if it was warm or cold. During warmup enrichment, there's quite a bit of extra fuel (hence the enrichment). Enough that it may not make a small leak noticeable.

Time to grab a can of carb cleaner or something similar and spray around the intake manifold. (and any other vacuum source for that matter).

i have the spi and it idles kinda rough and dies when i'd start it to run when it was like -30 actual temp out side, not counting the -50 windchill.. what should I check then? I don't know a whole lot of engine parts, but if pointed to the right spot I could make sure a connection is tight and true

I looked the engine over and over and over again for vacuum leaks but couldn't find any. I even tried spraying carb cleaner around the intake manifold and all vacuum lines. The intake manifold gasket does look like it's starting to flake apart though. I figured the carb cleaner would have narrowed down a leak but nada.

Trouble code: p0320 = Ignition engine speed input circuit.

So I removed the IAC valve today and cleaned it out real good and I also cleaned the MAF sensor and now it's idling even worse than before. Any thoughts? I don't think I could have screwed anything up.

Is there any way to actually test the IAC and see if it's working correctly? I'd hate to just waste money by throwing parts at it not knowing if that's for sure the problem.
